וְעַתָּ֖ה קְחוּ־לִ֣י מְנַגֵּ֑ן וְהָיָה֙ כְּנַגֵּ֣ן הַֽמְנַגֵּ֔ן וַתְּהִ֥י עָלָ֖יו יַד־יְהוָֽה׃
«現在你們給我找一個彈琴的人來。»彈琴的人彈琴的時候，永恆者的手就降在以利沙身上。
Rashi
Bring me a musician. Because of his anger, the Divine Presence departed from him.11See Maseches Pesachim 66b. Alternatively, Elisha was unable to prophesy because he was mourning Eliyahu’s departure. The Divine Presence does not reside with people who are sad. It rests on prophets only when they experience joy in their fulfillment of a mitzvah. See Maseches Pesachim 117a.
Metzudat David
Bring me a minstrel: To make me happy with his song, because of the anger Elisha had towards Yehoram, he did not receive prophecy, for prophecy is only received in happiness, and anger brings sadness
Metzudat David
When (the minstrel) played: When the minstrel began to play, the spirit of prophecy came to him (Elisha)
